Harmonic test plays an important role and function in traction power supply system. Based on the basic requirements of power system＇s harmonic test, analysis and appraisal were made to harmonic measurement methods both at home and abroad. It is pointed out that under asynchronous sampling conditions, the new method to realize non-linear circuit dynamic harmonic analysis and harmonic electric energy measurement is the new requirements for power system＇s harmonic test technology development. Mu- tual combination and coordination of harmonic test, harmonic analysis and harmonic treatment, measurement and control integration, intelligentizing and on-line harmonic measurement have become new harmonic study trend.
